PyQt6 no Windows: qtquickcontrols2windowsstyleimplplugin.dll: O módulo especificado não pôde ser encontrado

Estou tentando testar um código usando PyQt6. Quando tento exibir uma barra de menu no meu main.qml, recebo este erro:

QQmlApplicationEngine failed to load component
file:///C:/Users/[blablabla]/GUIt/main.qml:11:9: Type Menu unavailable
qrc:/qt-project.org/imports/QtQuick/Controls/Windows/Menu.qml:32:15: Type MenuItem unavailable
qrc:/qt-project.org/imports/QtQuick/Controls/Windows/MenuItem.qml:7:1: Impossible de charger la bibliothÞque C:\Users\[blablabla]\Python\Python313\Lib\site-packages\PyQt6\Qt6\qml\QtQuick\Controls\Windows\impl\qtquickcontrols2windowsstyleimplplugin.dllá: Le module spÚcifiÚ est introuvable.

(Desculpe, sou francês, então meus erros também, mas "Le module spÚcifiÚ est introuvable." significa "O módulo especificado não pôde ser encontrado")

Não consegui encontrar nenhum problema resolvido semelhante ao meu, então tentei a sorte aqui.

Estou no Windows 11 e estou usando Python3.13.3 (não a instalação nativa do Windows)

Aqui está meu código: main.py:

from PyQt6.QtWidgets import QApplication
from PyQt6.QtQml import QQmlApplicationEngine
from backend import Backend

app = QApplication([])
engine = QQmlApplicationEngine()

backend = Backend()
engine.rootContext().setContextProperty("pybackend", backend)

engine.load("main.qml")

if not engine.rootObjects():
    import sys
    sys.exit(-1)

app.exec()

backend.py:

    repoNameChanged = pyqtSignal()
    commitListChanged = pyqtSignal()

        self._repo_name = ""

    @pyqtProperty(str, notify=repoPathChanged)
    def repoPath(self):
        return self._repo_path

    @pyqtProperty(str, notify=repoNameChanged)
    def repoName(self):

        return self._commit_list

    @pyqtSlot()
    def chooseAndLoadRepo(self):
        dialog = QFileDialog()
        dialog.setFileMode(QFileDialog.FileMode.Directory)
        dialog.setOption(QFileDialog.Option.ShowDirsOnly, True)
        if dialog.exec():
            selected_dirs = dialog.selectedFiles()
            if selected_dirs:
                self.loadRepo(selected_dirs[0])  # charge le dossier sélectionné

    @pyqtSlot()
    def loadRepo(self, path = "C:/Users/lucie/Hesias/B2/MajorProject/major-project-b2"):
        try:

            self.repoNameChanged.emit()
        except Exception as e:
            print(f"Erreur : {e}")

    @pyqtSlot()
    def loadCommits(self):
        try:
            commits = [f"{c.hexsha[:7]}: {c.summary}" for c in self.repo.iter_commits()]
            print(commits)
            self._commit_list.setCommits(commits)
            self.commitListChanged.emit()
        except Exception as e:
            self._commit_list.setCommits([f"Erreur : {e}"])

        self._commits = commits
        self.endResetModel()
